This phase of the study will allow characterization of the health status of the population of HIV-positive pregnant women seeking care at the Gugulethu (Midwife Obstetric Unit)MOU and the services they receive. At their first antenatal clinic visit, women will be approached to complete Informed Consent #1, including consent for abstraction of routine clinic data on obstetric and HIV-related care. As part of this cross-sectional study, participating women will complete a short questionnaire and undergo phlebotomy.
